一、服务器域名配置

配置流程

配置参考URL：https://developers.weixin.qq.com/miniprogram/dev/api/api-network.html

二、nginx中配置反向代理加密websocket(wss)

upstream websocket{
 hash $remote_addr consistent;
 server 127.0.0.1:9090 weight=5 max_fails=3 fail_timeout=30s;
}
server {
 listen 80;
 server_name www.xxxx.cn;
 rewrite ^(.*)$ https://$host$1 permanent;
}
server
 { 
 listen 443;
  server_name www.xxxx.cn;
  ssl on;
  root /home/wwwroot/yzcp;
  index index.php index.html index.htm;
  ssl_certificate /usr/local/nginx/conf/cert/1526060965511.pem;#这里是服务端证书路径
  ssl_certificate_key /usr/local/nginx/conf/cert/1526060965511.key;#这里是密钥路径
  ssl_session_timeout 5m;
  ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4;
  ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
  ssl_prefer_server_ciphers on;
  ssl_verify_client off;

  location / {

   if (!-e $request_filename) {
    #一级目录
    rewrite ^(.*)$ /index.php?s=$1 last;
    break;
   }
   #wss配置
   client_max_body_size 100m;
   proxy_redirect off;
   proxy_pass http://websocket;#反向代理转发地址
   proxy_set_header Host $host;# http请求的主机域名
   proxy_set_header X-Real-IP $remote_addr;# 远程真实IP地址
   proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;#反向代理之后转发之前的IP地址
   proxy_read_timeout 604800s;#websocket心跳时间，默认是60s
   proxy_http_version 1.1;
   proxy_set_header Upgrade $http_upgrade;
   proxy_set_header Connection "Upgrade";
  }
  location ~ .+\.php {
   fastcgi_pass unix:/tmp/php-cgi.sock;
   fastcgi_index index.php;
   include fastcgi_params;
   set $path_info "";
   set $real_script_name $fastcgi_script_name;
